GEORGE S. BLAKESLEE, OF CHICAGO, ILLINOIS.

POTATO-FEELING- MACHINE.

To all whom it may concern:

Be it known that I, GEORGE S. BLAKESLEE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Potato-Peeling Machines,of which the following is a specification, reference being had to theaccompanying drawings.

My invention relates to potato peeling machines of the type in which thepeeling is removed by agitating the potatoes in contact withan abrasivesurface, and has for its object to provide certain improvements in themachine illustrated and described in my pending application Serial No.5:39AM, filed January 20, 1910, in which the receptacle and the rotarybottom on which the potatoes or other articles to be operated upon restare composed throughout of abrasive material, such improvements relatingparticularly to the construction of the bottom as hereinafter set forth.I accomplish this object as illustrated in the drawings and ashereinafter set forth,

What I regard as new is set forth in the claims.

In the accompanying drawings,Figure l is a front elevation of myimproved machine; Fig. 2 is a vertical section on line 22 of Fig. 1;Fig. 3 is a plan view of the bottom-plate; Fig. 4 is an under side viewthereof; and Fig. 5 is an edge view thereof.

My improved machine comprises a stationary receptacle cylindrical inform and having an aperture at the top for the admission of the potatoesor other articles to be operated upon. Said receptacle also is providedwith a bottom formed integral with the sides and having a spout ordischarge opening for the escape of water and parings,the receptaclebeing mounted on a suitable stand or pedestal which carries mechanismfor rotating the bottom-plate, the latter being mounted in the lowerportion of the rece tacle upon the upper end of a vertical sha driveneither by hand or power through the driving mechanism above referred to.Both the receptacle and the ro- Specification of Letters Patent.

Application filed September 25, 1911.

Patented Oct. 1, 1912. Serial No. 651,102.

tary bottom-plate are formed throughout of an abrasive substancecomposed of comminuted flint, or other suitable material, bondedtogether by cement or its equivalent substance that is of a lower degreeof hardness than the flint. so that in use the bonding materialdisintegrates more rapidly than the abrasive substance proper andconsequently the abrading surface is always sharp and effective. By thisconstruction the machine is made practically indestructible and cannotwear out since the walls of the receptacle and the bottom-plate are madeof such thickness that it is practically impossible to wear them out. 7

In my present invention a bottom-plate of improved construction isprovided to assist in moving the potatoes or other articles out towardthe inner wall of the receptacle so as to bring them more efiectivelyinto contact therewith, and also to cause the articles operated upon toroll over and thereby insure their being peeled completely. This isaccomplished by making the bottom-plate conical in form through thegreater portionof its area, the upper surface sloping downward to apoint near the margin, which is comparatively fiat. Small recesses orcups are provided, preferably at diametrically opposite points adjacentto the margin, which, in the rotation of the bottom-plate, has theeffect of causing the potatoes to roll more or less and thereby insurethe proper peeling thereof.-

Referring to the drawings for a description of the embodiment of myinvention therein shown,6 indicates the cylindrical receptacle in whichthe potatoes or other articles are placed, said receptacle having anintegral bottom 7 provided with a spout or outlet 8, as shown in Fig. 2.The receptacle 6, including the bottom 7, are made integral and arecomposed of comminuted flint or other suitable hard substance mixed withcement or other suitable bonding material.

9 indicate'san additional outlet adjacent to the bottom 7, the uppersurface of said bottom being inclined in opposite directions toward theoutlets 89 for the discharge of water and peelings.

10 indicates a door provided at one side of the receptacle 6 and alsoformed of the same material.

11 indicates standards or legs which support the receptacle 6.

12 indicates the inlet opening at the top of the receptacle. The legs 11are preferably made adjustable vertically so as to provide forregulating'the height of the receptacle 6 to any desired extent.

13 indicates cross-braces connected with the several legs and formingsupports for the driving mechanism.

14 indicates a vertical shaft mounted in suitable bearings on the braces13 and eX- t-ending up through a bearing 15 in the bottom 7. The shaft14 is provided with a beveled pinion 16 which meshes with a bevel dpinion 17 carried by a shaft 18 and provided with ahand-wheel 19, orother suitable means for rotating the same, as shown in Figs. 1 and 2.

20 indicates a water-pipe communicating with the upper portion of thereceptacle.

21 indicates the rotary bottom-plate, which is composed of the samematerial as the receptacle 6 and is mounted upon the upper end of theshaft 14 and connected to it so as to rotate therewith. As shown inFigs. 2, 3 and 5, the upper surface of the bottomplate is made convex orconical, sloping downward toward the margin thereof.

22 indicates recesses or cups in the bottomplate 21 adjacent to itsmargin, said recesses being large enough to receive a potato, apple, orother similar article. The marginal portion of the bottom-plate be tweenthe recesses 22 is substantially flat, as shown at 23, in Fig. 3.

24 indicates a handle for lifting the bottom-plate out of the receptaclewhen desired,

as for cleansing purposes.

When the potatoes or other articles are placed in the receptacle theyrest upon the bottom-plate 21. By rotating the latter the potatoes arecaused to roll more or less upon the bottom and are also carried aroundin contact with the inner wall of the receptacle so that by the actionof the abrasive surfaces they are effectively pared, the parings, andwater which is supplied during the operation, esca ing through theoutlets 89.

That w ich I claim as my invention, and desire to secure by LettersPatent, is,-

1.
